We study the rack-aware storage system where all nodes are organized in racks and within each rack can communicate freely without taxing bandwidth. Rack-aware regenerating codes (RRCs) were proposed for minimizing repair bandwidth single erasures. In initial setting of RRCs, a node requires participation remaining containing failed as well large number helper no failures. Consequently, may be i...

SUNITA SINGH, m.b., b.s. (Punjab) From the Brigade Laboratory, Allahabad Instead of the ordinary rectangular rack, a circular rotary rack has been used by us. The experimental tubes are rotated alongside the control tubes. The light comes from below after being reflected from a black surface. The readings are very clear and can be quickly made without disturbing the tubes. The rack consists of ...

OBJECTIVES The purpose of the study was to examine associations between bicycle helmet use and attitudes among U.S. college students. Bicycle helmet use was assessed for two different bicycle use purposes: commuting to school and recreation. MATERIALS AND METHODS Student bicycle riders were recruited on the campus of a large public university in Colorado. Questionnaire development was guided ...

A rack, which is the algebraic distillation of two of the Reidemeister moves, is a set with a binary operation such that right multiplication is an automorphism. Any codimension two link has a fundamental rack which contains more information than the fundamental group. Racks provide an elegant and complete algebraic framework in which to study links and knots in 3{manifolds, and also for the 3{...

Miniload automated storage and retrieval systems (AS/RSs) is a type of automatic storage and retrieval system that handles loads that are typically contained in small containers or totes, with load weights typically falling in the100 to 500 lb. In this paper, the open-rack structure with unidirectional-upward mobile loads within the rack is applied in miniload AS/RS, in which the stacker crane ...

Energy efficiency has become a very important concern for enterprise data centers due to the significant cost on electricity. To improve the energy efficiency of data centers, researchers and practitioners have proposed enormous work to reduce the energy consumption of data centers. Most of previous work focus on reducing the energy consumption of IT equipment; however, the power losses caused ...
